RDOS (Users)

Has anyone luck in trying RDOS?

I myself tried building it with no luck. Maybe a prebuilt virtual machine will be the choice.

If anyone is interested Leif Ekblad, the main project developer, provided me a bootable image: http://www.rdos.net/rdos/ShowVideoModes.zip

This is in the form of an IMG file. I tried to process the IMG file
inside WIN10 but I cet "corrupt" error messages. But I don't think
it is really corrupt.

Could someone give me some instructions please?

I don't have a floppy or CDDVD so I need to make a USB stick.

Thank you

I converted to VDI to mount it in an VM, but you can use https://www.askvg.com/win32-disk-imager-write-any-bootable-image-to-usb-drive-in-windows/ and create a bootable USB image.

After extracting I have a file named RDOS.BIN.

What do I do with this?

Using BinToIso I was able to make an ISO file from the BIN.
But I'm not sure it is good.

I used RUFUS to try to build a USB stick from this ISO which FAILED.

I tried to extract the ISO which also FAILED.

I need exact instructions.

RDOS

I took the RDOS.BIN file and put it on a USB stick formatted FAT32.

Then to see what happens I tried to boot from this USB stick.

I got a message a single line message sating that RDOS was loading
but nothing else, no other messages at all. I waited 15 minutes.

So now I really need help.

In my BIOS I selected to boot from the USB drive containing the RDOS
bin file.

This gives me q one lime message saying RDOS is starting but it does
not continue to boot after that.

Do you have RDOS installed and running?

I have GOOGLED all over for RDOS info but found nothing useful.

I looked at this website but found no helpful information other than
if RDOS is not already installed, installing the first time is hard.


Is there any way to contact this Leif guy for assistance?

I am myself stuck at trying it to boot without the VGA demo in VBox.
Maybe I need to recompile it and generated an RDOS.BIN without the demo at startup.

RDOS

Hi, I didn't know RDOS, it's new for me. I read the page and I tried to rebuild it from sources. The process is well described there. I got sources from SVN, installed OpenWatcom under WinXP, run BUILD.BAT and got no errors. Then I build the image from board/core2/MK.BAT that created OS image RDOS.BIN with kernel and necessary modules.
Did you read the Booting RDOS with GRUB bootloader paragraph? I think it's easy way to boot for nonUEFI users. You can use also grub4dos to boot from an existing DOS disk. So I put the files RDOS.BIN and GRUBLOAD.BIN and put lines
title RDOS
rootnoverify (hd0,0)
kernel /grubload.bin
modulenounzip /rdos.bin
to my grub's MENU.LST
but it crashed at boot. I try it on 2 different real PC and under BOCHS but only got the crash screen:

Anyway the RDOS is an impressive work I can't belive it was done by single (or few ?) person. The features are cool and match 21th century (multicore, long mode, acpi...) BUT I couldn't read anywhere on the page how it is compatible to existing DOS programs? There's only mention about Emulator for V86 so it may run some realmode programs. As it use multitasking and protection I think that it cannot run many DOS programs. And it's the weakness, all those shiny features against thousands of existing DOS programs. If so it's just another Menuet, tiny Linux, etc. class not a real usable DOS. It would be interesting if it could at least run DPMI programs or if there's some extension for DJGPP to produce RDOS executables. I can see that only OWC has RDOS as host and target.

I got the same crash also when tried image from ShowVideoModes.zip in BOCHS. Before it crashed I saw shortly a loading RDOS message and I also got APIC write length error by BOCHS that I ignored and clicked continue.

I tried to remove some modules from board/core2/rdos.cfg but all the effect was that I got same crash screen or the PC was restarted immediately.
I'm not sure if my compilation process is OK because I found that there are many *.err files containing some warings that was silenced in build.bat I don't know if they are serious, I'm not familiar with OWC. I would need some working RDOS.BIN for a reference that works on real HW or emulator. I don't have virtualbox installed so I used BOCHS...

And can you tell me if RDOS is able to run some DOS programs (COM/EXE RM/PM)?

Yes, you can use easily GRUB or GRUB4DOS to boot RDOS from HDD if you have read that paragraph on the site.

I am running a boot manager from TERABYTEUNLIMITED called BOOTITBAREMETAL
and I have been using this for over a decade. BOOTITBAREMETAL supports:

DOS MSDOS FREEDOS without needing a loader because these OS's have
their own loader/

Windows all versions are supported because these OS's don't need another
loader either.

Linux distrubitions for the same readons.

GRUB is a multiboot loader that can run most OSes like Windows, LINUX and many more. You can set up a section in the bootloader to run RDOS. Information about GRUB is here

" After you successfully installed GRUB onto your harddisk,
just add the following lines in a new section in MENU.LST: "

I am not going to remove BBM and try to use grub because, well
it may make RDOS work but I may well get DOS WINDOWS LINUX
difficulties which have been smooth sailing for a decade.

If you have some DOS installed you don't need to install anything else or change your existing bootloader. Just copy GRUB.EXE (from GRUB4DOS package), GRUBLOAD.BIN (RDOS web) and RDOS.BIN to your C: and add to MENU.LST:

title RDOS
rootnoverify (hd0,0)
kernel /grubload.bin
modulenounzip /rdos.bin

and then run GRUB.EXE from DOS.

Unfortunatelly all my trials with RDOS failed with crash or immediare reboot. I tried different OWC compilers, I rebuild RDOS.BIN many times with different driver configuratios but nothing. So I'm asking if somebody else make is successfully running.

I think I will have time to test On Wednesday.

A question though?

Does this mean that RDOS will be running on top of DOS
with all its inheritant things like 640K?

No, if you use grub4dos boot method it will rewrite DOS in memory and it will be no longer accessible.
